In table tennis speed glue is glue that is used to re-fix the rubber surfaces to the racket or paddle. Speed glue is usually applied around 30 minutes before a match starts. The use of speed glue has been found to increase the elasticity of the racket, which adds speed and spin to the ball. Speed glue works by its solvent vapours which make the porous cells of soft rubber expand. Wikipedia
